The Chinese People's Liberation Army (PLA) Eastern Theater Command has followed and monitored two German navy ships' transit through the Taiwan Straits, Naval Senior Captain Li Xi, spokesperson for the PLA Eastern Theater Command, said on Saturday.

The passage of the frigate "Baden-Württemberg" and supply ship "Frankfurt am Main" increase security risks and send wrong signals, said Li, adding that "Chinese troops will always be on high alert and resolutely counter threats and provocations of any forms."
